The colored squares in this spiral represent cards in the Little Square Deck of 36. The suit symbols and colors are apparent. Starting in the lower right hand corner, it reads clockwise. The suits are ordered as they are in the Codex. Consecutive pairs of suits are complementary, forming 3 sets of 12 cards: 9+3, 8+4, 7+5. Colors of longer wave length are associated with larger suits, shorter with smaller. In a rainbow, the larger, outer arcs are the warmer colors - red (9 cards), orange (8 cards), yellow (7 cards) - while the smaller, inner arcs are the cooler colors - green (5 cards), blue (4 cards), violet (3 cards).
